3,167,220 SLIDE SEALING LEQUII) DISPENSER Louis Koukal, 492 E. 78th St., New York, N.Y. Filed Get. 24, 1963, Ser. No. 318,713 3 Claims. ((1. 222477) This invention relates generally to a liquid dispenser such as disclosed in my Letters Patents 2,141,870, 2,141,- 871 and 2,519,479.

A principal object of the present invention is to provide a liquid dispenser that serves as a stopper for a bottle or other container of liquid.

Another object of the invention is to provide a liquid dispenser of this type wherein the discharge outlet and air vent are scalable by a slidable member.

A further object of the invention is to provide a liquid dispenser of this type that is adapted to be associated with a liquid measuring attachment.

Yet another object of the invention is to provide a liquid dispenser in the form of a cork stopper with a protective cover for the cork stopper.

Still another object is to provide a liquid dispenser which will ensure a more even flow of the liquid out of the bottle.

Still a further object is to provide a liquid dispenser that is simple in construction, economical to manufacture and highly eflicient in operation.

For further comprehension of the invent-ion, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings,

and to the appended claims in which the various novel 'features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 3 is a view looking from the left of FIG. 2.

FIG. 4 is a cross-sectional view taken on the line 44 of FIG. 3.

FIG. 5 is a perspective view of the slidable sealing valve.

FIG. 6 is an enlarged vertical sectional view of a liquid dispenser embodying a modified form of the invention bottle.

FIG. 7 is a sectional view through the center of the dispenser of FIG. 6 shown applied to the bottle and showing the neck of the bottle in tilted dispensing condition, the outlet being shown in sealed condition.

FIG. 8 is a view similar to FIG. 2 of a liquid dispenser embodying another modified form of the invention.

FIG. 9 is a perspective view of the protective sleeve for the cork stopper shown in FIG. 8.

FIG. 10 is an enlarged vertical sectional view taken on the line 10-10 of FIG. 9.

Referring now in detail to the drawings, in FIGS. 1 to 5, inclusive, a liquid dispenser embodying one form of the invention is shown and designated generally at 10. The dispenser 10 as shown in detail in FIG. 2, comprises a flat substantially triangular-shaped body 12 formed of plastic, metal or any other suitable material, terminating at one end, the bottom end as viewed in FIG. 2, in a plug extension 14, round in cros section, and reduced in diameter. An annular flange 16 is formed at the juncture of the body portion and extension. The

United States Patent 0 M 3,167,220 Patented Jan. 26, 1965 ICC body has .a smooth front 18, a smooth rear 20, smooth top 22 and smooth tapering sides 24 and 26.

An elongated opening or passage 28 is formed centrally through the body 12 and extension 14, intersecting the end of the extension. The opening extends perpendicularly near the wide end of the body and intersects the tapering side 24 of the body. A pipe 30 is fitted in the opening 28 and serves to discharge liquid, the outlet being disposed in the tapering side 24 of the body and being indicated at 32.

Another elongated opening or passage 34 is formed in the body and extension closely spaced from and disposed parallel to the opening 28 throughout the length of opening 28. A pipe 36 is fitted in opening 34. Pipe 36 is formed with an extension 38 protruding a considerable distance outwardly of the body extension 14 and forming a continuation of the pipe 36. Pipe 36 serves to admit air through air inlet 4% closely spaced from outlet 32. A cork sleeve cover 42 is fitted over the body extension 14, the outer surface of the cover tapering slightly downwardly and inwardly. A hole 44 is formed in the pipe extension 38 below the body extension 14 at approximately the inner end of a neck of a bottle when the dispenser is inserted into the neck of a bottle as shown in FIG. 1.

In accordance with the invention, a slidab le valve member 46 is provided for controlling the opening and closing of the discharge outlet 32 and air inlet 40. This valve member has a channel-shaped body 48 of sheet metal with opposed flanges 5i) along the long free edges thereof. The valve member is slipped over the side 24 of the body 12 with its flanges 5d, 50 riding in opposed elongated grooves 52, 52 formed in the surfaces of the front and rear 18 and 24), respectively, of the body 12. The grooves are disposed remote from the side 24 extending from a point above the air inlet 40 to a point below the midheight of the body 12 and slanting slightly downwardly and outwardly, that is, the bottom end of the grooves being slightly closer to the side 24 than the top end so that as the valve member rides upwardly the material of the valve member expands widening the space between the flange 5t 50 thereby releasably gripping the material of the body 12 to hold the valve member in closed position over the inlet and outlet.

In use, the pipe extension 38 and body extension 14 with cork 42 therearound are inserted into the neck 55 of a bottle 58 containing liquid L as shown in FIG. 1, the cork 42 plugging and sealing the neck of the bottle and the flange 16 seating on the outer edge of the neck. The body 12, when the dispenser is thus positioned, serves as a spout. When the bottle is in upright non-pouring position, the extra air vent hole 44 is generally disposed above the liquid level and the end of the air vent pipe extension 33 is disposed in the liquid, but when the bottle is tipped and disposed in pouring position as shown in FIG. 1, then the reverse is true and the air vent hole 44 is immersed in the liquid and the end of the air vent pipe 38 is above the liquid as shown in FIG. 1. Air bubbles will pass up through the liquid from the vent 44. A definitely more even flow of liquid follows due to the seeming stabilizing action of the hole 44. A manually measured amount of liquid may be poured out through the spout into a glass 64 as seen by the eye of the user.

In the modified form of the invention shown in FIGS. 6 and 7, the dispenser 10' is shown associated with an automatic liquid dispensing measuring device 64. The air vent pipe extension 3% extends nearly to the bottom of the bottle 5%, and the air vent hole 44 is disposed at a point where the neck 56' joins the body portion of the bottle.

The measuring device d4 includes a helical coil of wire 65 connected at one end to the inner end of the liquid dispensing pipe 30" andlat the other end is fastened to the air'vent pipe extension 38 in any suitable manner as by soldering. 'It is also soldered preferably at several points intermediateits-length .to pipe 38? which thereby provides a support fort he coilto keep it in parallel relation to the pipe 38". ,A valveseat 69 is formed on the inner end of dispensing pipe 30.

A ball valve member 68 is disp'osed'within the helical T coil 66,. the lower position thereof, as shown irrFIG. 6,

' being defined and limited bya stop member 70which is a cylindrical plug of any suitable material having a spiral groove therein to permit the plug to be advanced'or withdrawn along the axis of the coil. The operation of this ball in the coil is clearly setforth inmy issued Patents Nos.

2,141,870 and 2,141,871."

In all other respects, the dispenser 10"is similar to the dispenser 10 andsimilar referencenumerals are used to indicate similar parts. 1

In operation, the dispenser 10' functions similarly to the dispenser 10 except that a measured supply of liquid L is automatically dispensed by the measuring device 64 as follows 1' when the bottle'is in normal upright position,

the ball valve member 68 is at the bottom of the guiding I and timing coil. 66 resting on the adjustable stop member 70. For any position of. the ball member in this position,

'it will take a definite time for the ball member, when the bottle is tilted as shown in FIG. 7, to reach the valve seat 69 at the inner end of the liquid dispensing pipe 30' and shut off the flow of liquid. This provides a simple :means for determining in advance the amount of liquid to be poured out before the flow is interrupted. .By. adjusting the position of the stop member 70, the time above,

mentioned can be changed and therefore the amount either decreased or increased.

The modified form of dispenser 10'shown in FIGS. '8 to 10, inclusive, difiers from the dispenser 10 merely in that a hollow cylindrical protective cover. in the form 'of a split sleeve 74 of corkis. wrapped'a'round the cork cover 42". The sleeve 74 is formed with an annul'ar'bead i portion 76 atone end thereof, which head portion is reinforced by a wire 78. The ends of the sleeve. can readily be separated for slipping the sleeve over the cover 42" with the bead portion seating on the flange 16", of

the body 12" of the spout, the wire 78 holding the sleeve in snug position over the cover 42". V v
